DST, how can it be?

Why do I call it DST, instead of saying the words in the acronym? First of all, it is because the phrase is false advertising. Can they explain how it is they manage to save daylight? Can one place light and time in a vault, and save it? The answer to both questions is no. The phrase is deceptive; however, if one pronounces the words together, it sounds as if it can be done. The marketing strategy for it is fantastic. Now, spend most of the year on DST and then change back to normal Standard Time during the time of year when days start becoming shorter, and people will easily be convinced they believe they prefer DST. I will stop here.
